Description
Technical Field
[0001] This invention relates to the field of coil processing technology, and specifically to a device for shaping and cutting the leads of a ring coil. Background Technology
[0002] As a core component of intelligent transformers, intelligent reactors, DC converter transformers, and intelligent power distribution system equipment, toroidal coils are made of copper wire wound into a magnetic core. Their leads need to be connected to external circuits. The regularity of the shape and the consistency of the length of the leads directly affect the subsequent assembly efficiency and the reliability of electrical connections. Therefore, the shaping and cutting of the leads is a critical process. Currently, the shaping and cutting of coils mostly uses traditional semi-automatic devices. Generally, it requires manual placement of the toroidal coil on the device. Then, through simple positioning fixtures and visual observation by the operator, the coil's posture and position are adjusted. Multiple sets of warped or bent leads are aligned with the positioning holes or slots of the device and inserted into the positioning. The device is then started to shape and cut the leads. This process relies heavily on manual labor and is relatively cumbersome. Furthermore, the positioning accuracy by visual judgment is relatively low. When the leads are inserted into the positioning holes, they are prone to skewed insertion due to angular deviations. This leads to incomplete correction of the leads and deviations in length after cutting, which in turn affects the assembly accuracy with the power distribution equipment and the stability of electrical performance during use. In view of this, we propose a ring coil lead shaping and cutting device. Summary of the Invention
[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a ring coil lead wire shaping and cutting device, which effectively solves the problems of existing technologies that rely on manual adjustment of coil posture and alignment of lead wires one by one, resulting in high reliance on manual labor, cumbersome operation, low positioning accuracy, incomplete lead wire correction, and deviation in cutting length, thereby affecting subsequent assembly accuracy and the electrical performance stability of power distribution equipment.
[0004] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a device for shaping and cutting the lead wire of a ring coil, comprising a main body unit, including a bracket, multiple sets of insertion holes opened on the bracket, and a control console provided on the bracket; The unit includes a positioning unit, comprising a fixing mechanism mounted on a bracket for clamping a loop coil, a positioning mechanism mounted on the fixing mechanism, and an orthopedic mechanism mounted on the positioning mechanism for correcting the loop coil lead wire. The cutting unit includes a cutting mechanism disposed inside the bracket for shaping and cutting the lead wire of the ring coil, and a drive mechanism disposed inside the bracket for moving the cutting mechanism.
[0005] Furthermore, the fixing mechanism includes an electric cylinder fixedly connected to the top of the bracket, a fixing frame fixedly connected to the output end of the electric cylinder, and one side of the fixing frame slidably connected to the inner wall of the bracket.
[0006] Furthermore, the fixing frame is equipped with two sets of arc-shaped clamps for clamping the ring coil. Both sides of the two sets of arc-shaped clamps are fixedly connected to a fixing shaft. The end of the fixing shaft away from the arc-shaped clamps is rotatably connected to the inner wall of the bracket. A torsion spring is fixedly connected to the surface of the fixing shaft, and the other end of the torsion spring is fixedly connected to the inner wall of the bracket.
[0007] Furthermore, the positioning mechanism includes two electric cylinders fixedly connected to both sides of the fixed frame, and two L-shaped sliders fixedly connected to the output ends of the two sets of electric cylinders. The surfaces of the two sets of L-shaped sliders are slidably connected to the inner wall of the fixed frame, and conical positioning blocks for clamping and positioning the annular coil are fixedly connected to the sides of the two sets of L-shaped sliders that are close to each other.
[0008] Furthermore, the orthopedic mechanism includes two sets of electric telescopic rods whose inner walls are fixedly connected to each other. The output end of the electric telescopic rod is fixedly connected to an L-shaped slider, and the surface of the L-shaped slider is slidably connected to the inner wall of the L-shaped slider.
[0009] Furthermore, two sets of electric cylinders are fixedly connected to one side of the L-shaped slider two, and arc-shaped clamps are fixedly connected to the two output ends of the electric cylinders three.
[0010] Furthermore, the drive mechanism includes a limiting frame fixedly connected to the inner wall of the bracket. Both sides of the limiting frame are provided with electric cylinders four fixedly connected to the inner wall of the bracket. The output end of the electric cylinder four is fixedly connected to a push plate. The surface of the push plate is slidably connected to the inner wall of the bracket. A trapezoidal block is fixedly connected to the side of the push plate away from the electric cylinder four.
[0011] Furthermore, the foot-cutting mechanism includes a cutter fixedly connected to the side of the push plate away from the electric cylinder, an irregular plate corresponding to the trapezoidal block is provided above the cutter, an elastic telescopic rod two is fixedly connected to one side of the irregular plate, and the end of the elastic telescopic rod two away from the irregular plate is fixedly connected to the inner wall of the bracket.
[0012] Furthermore, a trapezoidal plate is provided above the irregularly shaped plate, and an elastic telescopic rod is fixedly connected to one side of the trapezoidal plate. The end of the elastic telescopic rod away from the trapezoidal plate is fixedly connected to one side of the push plate.
[0013] Furthermore, the control console is fixedly connected to the front side of the bracket, and can be used to control the operation of the positioning unit and the cutting unit.
[0014] The technical solution provided by this invention has the following advantages compared with known public technologies: This invention utilizes the automated coordinated action of the positioning unit, eliminating the need for manual adjustment of the coil posture and lead wire alignment. First, the arc-shaped clamping plate of the fixing mechanism, in conjunction with a torsion spring, initially clamps the coil. Then, the driving component of the positioning mechanism drives the positioning block to insert into the coil, automatically adjusting it to a vertically centered position. Simultaneously, the straightening mechanism pre-corrects the lead wire, ensuring accurate insertion into the insertion hole. This process reduces manual intervention, effectively improving work efficiency and enhancing the positioning accuracy of the coil and its lead wires. It prevents issues such as skewed insertion after the lead wire is inserted into the insertion hole, which could lead to incomplete correction and length deviation after cutting during subsequent shaping and trimming. Simultaneously, by utilizing the trapezoidal blocks and irregular plates of the cutting unit, and the staggered clamping of the trapezoidal plates, along with the limiting frame, secondary shaping of the lead wire is achieved. At the same time, the cutter is driven to cut along the preset stroke, which can further improve the shaping and cutting quality and efficiency of the toroidal coil lead wire, and ensure the assembly accuracy with the power distribution equipment and the electrical performance stability during use.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0019] The present invention will be further described below with reference to embodiments.
[0020] like Figures 1 to 9 As shown, a ring coil lead wire shaping and cutting device includes a main unit 100, a bracket 101, multiple sets of insertion holes 102 on the bracket 101, and a control console 103 on the bracket 101. The control console 103 is fixedly connected to the front side of the bracket 101 and can be used to control the operation of the positioning unit 200 and the cutting unit 300. The control console 103 is located on the front side of the bracket 101 and is connected to the electronically controlled drive components in the positioning unit 200 and the cutting unit 300 via power cords. It can also be connected to an external power supply via power cords to control the electronically controlled drive components in the positioning unit 200 and the cutting unit 300. The insertion holes 102 on the bracket 101 facilitate the insertion of the ring coil lead wire into the bracket 101, thereby cooperating with the cutting unit 300 and the positioning unit 200 to shape and cut the ring coil lead wire. Furthermore, the positioning unit 200 includes a fixing mechanism 201 mounted on the bracket 101 for clamping the annular coil. The fixing mechanism 201 includes an electric cylinder 2011 fixedly connected to the top of the bracket 101. A fixing frame 2012 is fixedly connected to the output end of the electric cylinder 2011. One side of the fixing frame 2012 is slidably connected to the inner wall of the bracket 101. Two sets of arc-shaped clamping plates 2013 for clamping the annular coil are provided inside the fixing frame 2012. The two sets of arc-shaped clamping plates 2013... Fixed shafts 2014 are fixedly connected to both sides. The end of the fixed shaft 2014 away from the arc-shaped clamp 2013 is rotatably connected to the inner wall of the bracket 101. A torsion spring 2015 is fixedly connected to the surface of the fixed shaft 2014, and the other end of the torsion spring 2015 is fixedly connected to the inner wall of the bracket 101. The inner walls of both sets of arc-shaped clamps 2013 are provided with smooth rubber pads, which can ensure the stability of clamping the ring coil and avoid wear on the copper wires on the coil during the clamping process. It should be noted that when performing the shaping and trimming of the lead wire of the toroidal coil, the toroidal coil can first be clamped in the two sets of arc-shaped clamps 2013. The torsion spring 2015 on the fixed shaft 2014 can provide the two sets of arc-shaped clamps 2013 with clamping force to initially fix the coil. After the coil positioning is completed and the lead wire is shaped, the coil can be driven down through the electric cylinder 2011 and the fixing frame 2012 to insert the lead wire into the insertion hole 102 and perform the shaping and trimming of the lead wire. Specifically, a positioning mechanism 202 is installed on the fixing mechanism 201. The positioning mechanism 202 includes two electric cylinders 2021 fixedly connected to both sides of the fixing frame 2012. The output ends of the two sets of electric cylinders 2021 are fixedly connected to L-shaped sliders 2022. The surfaces of the two sets of L-shaped sliders 2022 are slidably connected to the inner wall of the fixing frame 2012. On the side of the two sets of L-shaped sliders 2022 that are close to each other, a conical positioning block 2023 for clamping and positioning the ring coil is fixedly connected. The surfaces of the two sets of conical positioning blocks 2023 are provided with a smooth rubber layer. At the same time, the diameter of the thickest part of the conical positioning block 2023 is close to the inner diameter of the ring coil. When the two sets of conical positioning blocks 2023 are close to each other, the conical positioning block 2023 can be inserted into the ring coil. During the insertion process, the position of the ring coil can be adjusted so that the ring coil is in a vertical state. It should be noted that by using the output of two sets of electric cylinders 2021, the conical positioning block 2023 can be moved by two sets of L-shaped sliders 2022 to adjust the position of the ring coil and clamp the ring coil so that the ring coil is vertical and can be kept in the center position, so that the coil lead wire can be accurately inserted into the insertion hole 102 of the bracket 101 later. Specifically, there is a correction mechanism 203 installed on the positioning mechanism 202 for correcting the lead wire of the ring coil. The correction mechanism 203 includes two sets of electric telescopic rods 2034 whose inner walls are fixedly connected to the two sets of L-shaped sliders 2022. The output end of the electric telescopic rod 2034 is fixedly connected to an L-shaped slider 2031. The surface of the L-shaped slider 2031 is slidably connected to the inner wall of the L-shaped slider 2022. Two sets of electric cylinders 2032 are fixedly connected to one side of the L-shaped slider 2031. The two output ends of the electric cylinders 2032 are fixedly connected to arc-shaped clamps 2033. The inner wall of the arc-shaped clamps 2033 is provided with a smooth rubber layer. When the electric cylinders 2032 output, the two sets of arc-shaped clamps 2033 connected to each set of electric cylinders 2032 can move closer to each other. The two sets of arc-shaped clamps 2033 after moving closer can form a ring, but the inner diameter of the ring is slightly larger than the diameter of the coil copper wire. It should be noted that while the second electric cylinder 2021 moves the L-shaped slider 2022 closer to the coil, it can simultaneously move the arc-shaped clamping block 2033 on the third electric cylinder 2032 closer to the coil's lead wire. During this approach, the two sets of arc-shaped clamping blocks 2033 on the third electric cylinder 2032 are in a state of distance from each other. Only after the conical positioning block 2023 has completely clamped the coil is the third electric cylinder 2032 activated, causing the two sets of arc-shaped clamping blocks 2033 to close. At this point, the arc-shaped clamping block 2033 is at the position closest to the magnetic core of the copper wire lead-out section. The copper wire lead-out section may experience varying degrees of warping and bending during the initial processing, but the position closest to the wire core will not be warped. The coil has a large warp and bend, so when the electric cylinder 2032 drives the two sets of arc-shaped clamps 2033 to close, the two sets of arc-shaped clamps 2033 can form a ring around the copper wire lead-out part. After the copper wire lead-out part is ringed, the electric telescopic rod 2034 can be activated, thereby driving the L-shaped slider 2031 to descend, and driving the electric cylinder 2032 and the arc-shaped clamps 2033 to descend. During the descent, the two sets of arc-shaped clamps 2033 corresponding to each set of copper wire lead-out feet can complete the correction and shaping of the warp and bend of each set of copper wire lead-out feet, so that the coil copper wire lead-out feet are in a relatively vertical state, which makes it easy for the lead-out feet to be accurately inserted into the insertion hole 102. It should be noted that after the coil is fully positioned and the coil lead wire is straightened, the electric cylinder 2011 can be activated to drive the coil held by the fixing frame 2012 and the arc-shaped clamp 2013 to descend. At the same time as it descends, the electric telescopic rod 2034 is activated to retract, which drives the electric cylinder 2032 and the arc-shaped clamp 2033 used to straighten the coil lead wire to rise, so as to avoid interference with the descent of the coil and the insertion of the coil lead wire into the insertion hole 102. Through the output of the electric cylinder 2011, the coil descends, and the straightened lead wire can be accurately inserted into the insertion hole 102 of the bracket 101. Furthermore, the cutting unit 300 includes a cutting mechanism 302 disposed inside the bracket 101 for shaping and cutting the lead wire of the ring coil. The cutting mechanism 302 includes a cutter 3025 fixedly connected to the side of the push plate 3012 away from the electric cylinder 3011. Above the cutter 3025 is a shaped plate 3022 corresponding to the trapezoidal block 3013. A second elastic telescopic rod 3024 is fixedly connected to one side of the shaped plate 3022. The end of the second elastic telescopic rod 3024 away from the shaped plate 3022 is fixedly connected to the inner wall of the bracket 101. Above the shaped plate 3022 is a trapezoidal plate 3021. A first elastic telescopic rod 3023 is fixedly connected to one side of the trapezoidal plate 3021. The first elastic telescopic rod 3023 is located away from the trapezoidal plate 3021. One end is fixedly connected to one side of the push plate 3012; the trapezoidal plate 3021 is above the irregular plate 3022, and the cutter 3025 is below the irregular plate 3022, ensuring that the three will not collide or interfere during movement. At the same time, the trapezoidal plate 3021 and the irregular plate 3022 can form an interlaced state during movement, thereby positioning the lead wire inserted into the insertion hole 102 and further straightening and shaping the lead wire. The cutter 3025 can be used to cut the straightened and positioned lead wire, so that each lead wire of the coil can be in a relatively vertical state and consistent in length, ensuring accurate adaptation to the subsequent circuit installation, such as insertion into PCB board holes and soldering, and ensuring stable and reliable electrical connection. Specifically, there is a drive mechanism 301 installed inside the bracket 101 to drive the cutting mechanism 302 to move. The drive mechanism 301 includes a limiting frame 3014 fixedly connected to the inner wall of the bracket 101. Both sides of the limiting frame 3014 are provided with electric cylinders 3011 fixedly connected to the inner wall of the bracket 101. The output end of the electric cylinders 3011 is fixedly connected to a push plate 3012. The surface of the push plate 3012 is slidably connected to the inner wall of the bracket 101. A trapezoidal block 3013 is fixedly connected to the side of the push plate 3012 away from the electric cylinders 3011. It should be noted that after the coil lead is inserted into the insertion hole 102, the electric cylinder 3011 can be activated. The push plate 3012 drives the trapezoidal plate 3021 on the elastic telescopic rod 3023 towards the lead. Simultaneously, the inclined surface of the trapezoidal block 3013 presses against the inclined surface of the irregular plate 3022, causing the irregular plate 3022 to also move towards the lead. This creates an interlaced state between the irregular plate 3022 and the trapezoidal plate 3021. Combined with the limiting frame 3014 and the insertion hole 102, this allows for shaping, positioning, and clamping of the coil lead. As the electric cylinder 3011 continues to output power, the side of the trapezoidal plate 3021 away from the push plate 3012 contacts the surface of the limiting frame 3014. At this point, the trapezoidal plate 3021 stops moving, and the elastic telescopic rod 3023... The contraction occurs, and simultaneously the trapezoidal block 3013 and the inclined surface of the irregular plate 3022 disengage. As the push plate 3012 moves, the trapezoidal block 3013 moves, while the irregular plate 3022 stops moving but maintains clamping on the coil lead wire. The cutter 3025 located below the irregular plate 3022 continues to move with the output of the electric cylinder 3011. Through the setting of the limiting frame 3014, after the lead wire is inserted into the insertion hole 102, it can abut against the side of the lead wire away from the cutter 3025. The surface of the limiting frame 3014 is also provided with a strip groove larger than the thickness of the cutter 3025. Thus, during the continuous movement of the cutter 3025, it can move into the strip groove of the limiting frame 3014 and complete the cutting of the coil copper wire lead wire, realizing the shaping and cutting work of the coil copper wire lead wire.
[0021] The working principle of the present invention: The device uses the main body unit 100 as the core support frame, wherein the bracket 101 provides a stable mounting carrier for the positioning unit 200 and the cutting unit 300, and the multiple sets of insertion holes 102 opened on the bracket 101 provide a precise insertion channel for the lead wire of the ring coil, ensuring that the lead wire can enter the processing area of the cutting unit 300 vertically. The control console 103 is fixed to the front of the bracket 101 and is connected to the electric cylinder 1 2011, electric cylinder 2021, electric cylinder 3 2032, electric telescopic rod 2034 of the positioning unit 200 and the electric cylinder 4 3011 of the foot cutting unit 300 through power cords. As the electric control center, it realizes the stroke setting, timing control and action linkage of each driving component to avoid structural interference. The specific stroke setting and timing control program can be set according to manufacturing requirements, etc. The positioning unit 200 is the core to ensure the accuracy of subsequent shaping and cutting. Through the progressive actions of the fixing mechanism 201, the positioning mechanism 202 and the straightening mechanism 203, the coil fixing, posture calibration and lead wire pre-correction are completed. The annular coil with copper wire is placed between the two sets of arc-shaped clamps 2013 of the fixing mechanism 201, either manually or through external robotic arms or other automated equipment. The arc-shaped clamps 2013 are rotatably connected to the inner wall of the bracket 101 through the fixing shaft 2014. One end of the torsion spring 2015 on the surface of the fixing shaft 2014 is fixed to the inner wall of the bracket 101 and the other end is fixed to the fixing shaft 2014. The elastic restoring force of the torsion spring 2015 drives the two sets of arc-shaped clamps 2013 to clamp towards the center of the coil, realizing the initial fixing of the coil. At the same time, the inner wall of the arc-shaped clamps 2013 is provided with a smooth rubber pad layer, which not only ensures the clamping stability, but also avoids wear on the copper wire on the surface of the coil. The electric cylinder 2011 of the fixing mechanism 201 is fixed to the top of the bracket 101, and its output end is connected to the fixing frame 2012. One side of the fixing frame 2012 is slidably connected to the inner wall of the bracket 101. The electric cylinder 2011 receives the command from the control console 103 and can then drive the fixing frame 2012 and the clamped coil to rise and fall, so as to achieve precise alignment of the lead wire and the insertion hole 102. The electric cylinders 2021 fixed on both sides of the fixing frame 2012 receive the command from the control console 103 to extend and push the L-shaped slider 2022 connected to the output end to slide along the inner wall of the fixing frame 2012. The two sets of L-shaped sliders 2022 are fixed with conical positioning blocks 2023 on the side that are close to each other. The surface of the conical positioning block 2023 is provided with a smooth rubber layer, and the diameter of the thickest part is close to the inner diameter of the ring coil. As the L-shaped slider 2022 moves, the conical positioning block 2023 is gradually inserted into the coil. During the insertion process, the coil posture is adjusted to a vertical state by the guiding effect of the conical surface, and the coil is placed in the center position of the fixing frame 2012. This ensures that the coil lead wires can be evenly aligned with the insertion holes 102 on the bracket 101, avoiding the problem of lead wire alignment deviation caused by the offset of the ring coil. While the positioning mechanism 202 is in motion, the control console 103 sends a command to the electric telescopic rod 2034 of the orthopedic mechanism 203. The electric telescopic rod 2034 is fixed to the inner wall of the L-shaped slider 1 2022, and its output end is connected to the L-shaped slider 2 2031, which drives the L-shaped slider 2 2031 to slide along the inner wall of the L-shaped slider 1 2022, so that the two sets of electric cylinders 3 2032 fixed on one side of the L-shaped slider 2 2031 are close to the coil lead wire. In the initial state, the two sets of arc-shaped clamping blocks 2033 connected to the output end of the electric cylinder 2032 are in a separated state. After the conical positioning block 2023 fully clamps the coil, the control console 103 controls the electric cylinder 2032 to retract, so that the two sets of arc-shaped clamping blocks 2033 close together. The inner diameter of the ring formed after closing is slightly larger than the diameter of the copper wire, and the clamping position is selected to be near the magnetic core without obvious warping. Therefore, the copper wire is close to the magnetic core and is subject to corresponding constraints, and its shape is relatively regular. Subsequently, the electric telescopic rod 2034 receives the descent command from the control console 103, which drives the L-shaped slider 2031, the electric cylinder 2032 and the arc-shaped clamp 2033 to descend synchronously. During the descent, the arc-shaped clamp 2033 constrains the warped part of the lead wire, corrects the irregularly bent copper lead wire to a relatively vertical state, completes the pre-correction, and avoids jamming or positioning deviation when inserting the lead wire into the insertion hole 102 due to the bending of the lead wire. After pre-correction, the control console 103 sends a descent command to the electric cylinder 2011. The electric cylinder 2011 pushes the fixing frame 2012 down along the inner wall of the bracket 101, causing the coil held by the arc-shaped clamping plate 2013 to descend synchronously. At the same time, the control console 103 controls the electric telescopic rod 2034 to retract, causing the L-shaped slider 2031, the electric cylinder 2032 and the arc-shaped clamping block 2033 to rise, avoiding interference with the insertion of the lead wire. Finally, the pre-corrected copper wire lead wire is accurately inserted into the insertion hole 102 of the bracket 101, and the lower end of the lead wire extends to the processing area of the cutting unit 300 inside the bracket 101, completing the alignment. At this time, the control console 103 sends an extension command to the electric cylinder 3011 of the cutting unit 300. The electric cylinder 3011 is fixed to the inner wall of the bracket 101, and its output end is connected to the push plate 3012. The surface of the push plate 3012 is slidably connected to the inner wall of the bracket 101. Under the push of the electric cylinder 3011, it moves horizontally towards the lead-out line. The side of the push plate 3012 away from the electric cylinder 3011 is fixed with a trapezoidal block 3013. At the same time, the push plate 3012 is connected to the lead-out line by an elastic telescopic rod. A trapezoidal plate 3021 is connected to a push plate 3012. As the push plate 3012 moves, the trapezoidal block 3013 contacts the inclined surface of the irregular plate 3022 of the cutting mechanism 302. The elastic telescopic rod 3023 drives the trapezoidal plate 3021 to move towards the lead-out line in sync, realizing the transmission of power to the cutting mechanism 302. The limiting frame 3014 fixed on the inner wall of the bracket 101 limits the movement of the push plate 3012 and the subsequent cutter 3025, ensuring that the movement stroke is accurate and controllable. The trapezoidal block 3013, driven by the push plate 3012, presses the inclined surface of the irregular plate 3022, causing the irregular plate 3022 to overcome the elastic force of the elastic telescopic rod 3024 and move closer to the lead wire. At the same time, the trapezoidal plate 3021 also moves towards the lead wire. The trapezoidal plate 3021 and the irregular plate 3022, together with the limiting frame 3014, form an interlaced clamping of the lead wire inserted into the insertion hole 102, realizing the secondary shaping of the lead wire, further correcting any minor deviations that may exist after pre-shaping, and ensuring that the copper wire lead wire is completely vertical. When the trapezoidal plate 3021, on the side away from the push plate 3012, comes into contact with the surface of the limit frame 3014, the trapezoidal plate 3021 stops moving, and the elastic telescopic rod 3023 is compressed and contracted. At this time, the control console 103 controls the electric cylinder 3011 to continue to extend, and the push plate 3012 drives the trapezoidal block 3013 and the cutter 3025 to continue to move. After the trapezoidal block 3013 separates from the inclined surface of the shaped plate 3022, the shaped plate 3022 maintains the clamping state of the lead wire under the restoring force of the elastic telescopic rod 3024, so as to avoid the lead wire from shifting when cutting. Finally, the cutter 3025 moves continuously toward the limit frame 3014 under the drive of the push plate 3012. Because the limit frame 3014 has a strip groove on its surface that is thicker than the cutter 3025, the cutter 3025 extends into the strip groove to cut the copper wire leads after clamping and positioning, ensuring that the length of each lead is consistent, which is convenient for the subsequent welding or insertion into the PCB board of the intelligent transformer and reactor coil. After the cutting is completed, the control console 103 sends a reset command to each drive component. The electric cylinder 3011 retracts, driving the push plate 3012, cutter 3025, trapezoidal block 3013 and trapezoidal plate 3021 back to their initial positions. The elastic telescopic rods 3023 and 3024 reset, and the trapezoidal plate 3021 and the irregular plate 3022 disengage from the lead wire. The electric cylinder 2011 rises, driving the fixing frame 2012 and the coil to reset. The electric cylinder 2021 extends and the electric cylinder 2032 retracts, causing the conical positioning block 2023 and the arc-shaped clamping block 2033 to disengage from the coil. The finished ring coil is then manually removed, and the device returns to its initial state, waiting for the next operation.
